MACHINE FOR WINDING BOBBINS.

SPECTIFICATION forming part of Letters Patent No. 364,694, dated June 14, 1887.

Application tiled February 11, 1887. Serial No. 227,274. (No model.)

.To all whom it may concern..-

Beit known that I, CHESTER F. WICKWIRE, a citizen of the United States, residing at Cortland, in the county of Cortland and State of New York, have invented certain new and useful Improvementsin Machines for Winding Bobbins, of which the following is a specification,refere nee being had therein to the accom- This invention relates to a machine designed more particularly for winding thread on the .class of bobbins which have at opposite ends -of the spool large annular flanges or disks which are generally convexed on their outer sides.

The invention consists in an improved construction and combination of parts, constituting a machine which is simple, compact, and comparatively inexpensive in its construction and efficient and convenient in its operation, as hereinafter describedfand specifically set forth in the claim. v

The invention is fully illustrated in the annexed drawings, wherein Figure 1 is a side elevation of my improved bobbin-winder with the bobbin in position for winding the thread thereon, and Fig. 2 is a vertical longitudinal section of the same, showing parts in elevation.

A and A denote two pillow-blocks, which are arranged axially in line with each other, and are rigidly attached to or formed integral with one and the same base-plate,D, by which they are'secured to a table or bench or other suitable support.

The pillow-block A is formed with two journal boxes or bearings, B B, in which is journaledthe spindle a, which is restrained from longitudinal movement by an abutment, c, secured in one of the bearings B at the heel of the spindle by a set'screw, s, inserted vertically or transversely into the said bearing and engaging the top or side of the abutment, as shown in Fig. 2 of the drawings. The spindle a protrudes at the end of the pillow-block adjacent to the other pillow-block, and has secured to it a head, 0, the hub of which abuts against the pillow-block, and has a set-screw, t,passing throughit and engaging the spindle. This head is of the form of a disk, which is concave on the side facing toward the pillowblock A, the concavity thereof corresponding to the usual convexity of theside of the bobbin. 1? represents the driving-pulley, which is securedto the spindle a between the two bearings B B, the spindle being thus supported at opposite sides of the said pulley.

The pillow-block A is formed with a pro longed journal-box, B, and in this is mounted the spindle a, which is adapted to rotate and also slide longitudinally therein. To the end of the spindle a facing the head 0 is attached a head, 0, and the opposite end of said spindle is extended only part way thelength of the bearing B, and back of said end of the spindle and in the bearing is arranged a push-bar, b, which projects through the end of the bearing B, and is connected at its outer end to one of the arms of a bell-crank or elbow lever, Z, pivoted on the base D. The otherarm ofsaid lever may be arranged to be operated by hand; but I prefer to connect to it a pitman, d, to be operated by a spring-supported treadle of the usual style, not necessary to behere illustrated. In operating the described bobbin-winder the spindle a is to be retracted or pushed back toward the pillow-block A a sufficient distance to allow the bobbin I to be introduced between the two heads 0 G; then by pressing down the treadle the lever Z is caused to push the spin dle a toward the bobbin and press the head 0 against the side of the bobbin, the latter being thus clamped between the two heads 0 O. The concave face of the head 0, having a frictional hold on the bobbin, compels the lat ter to rotate with the driving-spindle a.

When the bobbin is filled with thread, its motion is instantaneously stopped by releasing the pressure from the lever l, and thus relieving the spindle a from the pressure of the push-bar b. The said spindle can then be pushed toward the pillow-block to allow the bobbin to drop from between the two heads 0 0.

Having described my invention, what I claim as new, and desire to secure by' Letters Patent, is

The combination of the pillowblock A, formed with two bearings, B B, the spindle A in said bearings, the pulley P, attached to said spindle between the bearings, the abutment c, secured in one of the bearings at the end of 'the spindle, the head 0, secured to the opposite end of the spindle, the pillow-block A, axially in line with the other pillow-block,

the spindle a, movable longitudinally in the oftwo attestin pillow-block A, the head 0, secured to said spindle at the end adjacent to the other spindle, the push-bar I) at the opposite end of the spindle a, and the lever Z, for actuating said push-bar, substantially as described and shown.

In testimony whereof I have hereunto signed 10 my name and affixed my seal, in the presence g witnesses, at Cortland, in the county of Cortland, in the State of New York, this 4th day of February, 1887.
